WILLIAM PLETTNER, OF TRINIDAD, COLORADO.

SIGHT FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 295,425, dated March 18, 1884.

Application filed December 26, 1883. (No model.)

10 all whom it may concern:

Be it known that I, WILLIAM PLETTNER, a citizen of the United States, and a resident of Trinidad, in the county of Las Animas and State of Colorado, have invented certain new and useful Improvements in Breech-Sights for Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure l is a side elevation of the Vernierbar of a rifle or gun provided with my improved sight. Fig. 2 is a front elevation of the same with the sight removed. Fig. 3 is a detail view of the sight, showing the construction of the wind-gage and removable spiritlevel. Fig. 4 is a detail view of the disk with the gage-slide removed. Fig. 5 is a detail view of the slide. Fig. 6 is a cross-section of the same through line w m in Fig. 5. Fig. 7 is a detail view of the support or holder for the spirit-level.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to the breechsights of rides and other fire-arms, adapted to be used with the ordinary graduated vernierbar for long-range shooting; and it consists in the construction of a wind-gage whereby allowance may be made for windage in working the gun, as hereinafter more fully described and claimed.

In the accompanying drawings, A is a vernier-bar; B, the graduated scale of the same,

and Gthescrew forraising or loweringthesight. The latter consists of a circular disk, D, having a central square ap'erture, E, which is in tersected by a groove or recess, 0. In this groove slides the plate F, in the center of which is a sight-hole, f. Plate F is provided with-brackets G, having caps II at their outer ends, which support a small spirit-level, I. One of these caps is provided with a springtop, (shown at h in Fig. 7,) by raising or unclasping which the spirit-level may readily be lifted out and removed from its conical caps or holders H. The plate F, with its level I, may be moved forward and back in the recessed disk D by means of a finely-threaded screw, J, in a manner well understood, by means of which it will be seen that the sighthole f may be adjusted to the right or to the left to compensate for windage.

Having thus described my invention, I claim and desire to secure by Letters Patent 'of the United States The combination of the disk D, having central square aperture, E, and horizontal groove or recess 0, intersecting the same, slide F, having sight-hole f and brackets G, constructed with the conical holders I-I, removable spiritlevel I, and means for adjusting the slide upon the disk, substantially as shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
